BOX.

Application filed April 11, 1927. Serial No. 182,751.

My invention has for its object to provide a triangular box formed froma single blank, and to this end it consists of the novel constructionand arrangement of parts hereinafter described and defined 1n theclaims.

The improved box. while intended for general use, is especially adaptedfor bolding a single cut of pie.

In the accompanying drawings, which illustrate the invention, likecharacters indicate like parts throughout the several views.

Referring to the drawings:

Fig. 1 is a plan view of the blank showing one form of the box;

Fig. 2 isa perspective view showing the blank folded to form a box:

Fig. 3 is a view in section taken on the line 3-3 of Fig. 2; and

Fig. 4 is a View corresponding to Fig. 2 but showing a slightmodification in the lock tongue.

The numeral 5 indicates a single blank from which the triangular boxshown in Figs. 2 and 3 is formed. This blank. 5 be formed from anysuitable material as relatively stitt' paper stock, and comprises atriangular bottom member 6, two rectangular side members 7 and 8, arectangular secondary cover member 9, a rectangular main cover member10, a rectangular end member 11, tucks 12, 13 and 14., a tuck 15, and alock tongue 16.

The end members 7 and 8 are formed at the s des of the bottom member 6and the cover members 9 and 10 are formed at the outer longitudinaledges of the end members 7 and 8, respectively. The end member 11 isformed at the. base of the main cover member 10. The flaps 12 and 13 arefornied with the ends of the side members 7 and 8 at the base of thebottom member 6. and the flap 14 is formed with the other end of theside member 7. The tuck 15 is formed at the outer longitudinal edge ofthe end member-11. The tongue 16 is formed with the bottom member 6 atthe base thereof. A lock slot 17 for the tongue 16 is formed between themain cover mem ber 10 and the end member 11.

The blank 5 is scored or cut creased to form folding lines. a betweenthe bottom member 6 and side members 7 and 8; fold ing lines 6 betweenthe end member 7 and mag sue supplemental cover 9 and the side member 8and the main cover 10; folding lines a between the end members 7 and 8and tucks 12, 13 and 14; folding line d between the main cover member 10and end member 11; folding line e between the end member 11 and tuck 15; folding line f between the bottom member 6 and tongue 16; and foldingline 9 in said tongue.

To form the box shown in Fig. 2 from the blank 5 shown in Fig. 1, thesides 78 are first folded on the lines a. The tucks 12, 13 and 14 arenext folded inward on the lines a. The secondary member 9 is then foldedon its line b and onto said tucks into a position in which it isparallel with the bottom member 6. The main cover 10 is then folded onits line b and onto the secondary cover 9. The end member 11 is thenfolded on the line 03 until stopped. by the tucks 12 and 13. and itstuck 15 is then inserted into the box between the tucks 12 and 13 andthe bottom member 6, and finally the tongue 16 is folded on the line finto fiat engagement with the end member 11 and thenfolded again on theline 9, and

its free end slot 17.

From the above description it is evident that the box is formed from asingle p ece of material and without the use of glue or other fasteningmeans.

The structure defined in Fig.4 is the same as that shown in Fig. 1 withthe exception of the tongue 18 which is inserted through a slit 19 inthe transverse center portion inserted through the of the, end member11.

What I claim is:

1. A triangular box-forming blank having folding lines arranged to forman intermediate triangular bottom member, two rectangular side members,one at each side of the bottom member, a triangular cover member at theouter side of one of the side members, an end member at the base of thecover member, a triangular secondary cover member at one side of one ofthe side members, tucks at certain of the ends of the side members, aflap formed with the outer longitudinal edge of the end member, and atongue formed with the bottom member at the base thereof and arranged tobe inserted through a slit in the end member, whereby when the blank isfolded a triangular box is formed having but one free edge at the topand one free edge at. the bottom, said free edges being disposed at anangle to each other.

2. A foldable triangular box formed from a. single blank closed at itstop, bottom and sides, said blank being so shaped and scored as toprovide when folded only one free edge at the top and one free edge atthe bottom, the vertically spaced free edges extending parallel Withdiiierent sides of the box.

3. A foldable box comprising superimposed triangular top portions, atriangular bottom portion, and two rectangular side portions connectingsaid top and bottom portions in series, and a third rectangular sideport-ion forming an integral extension of one of said to portions havingmeans frictionally engaglng with said bottom portion. whereby only onefree edge is provided at the top and at the bottom of the folded 4. Afoldable triangular box blank in a single piece scored between itsmarginal edge to provide a triangular bottom portion and two triangulartop portions connected to opposite sides of said bottom portion byintermediate rectangular side portions providing four connected sides ofa triangular box when folded with one free edge, and 2.

rectangular extension of one of said top members forming the fifth sideof said box and having a flap adapted to frictionally engage said bottomportion providing a second free edge extending atan angle to the freeedge aforesaid and on the opposite side of the folded box.

.5. A foldable triangular container in a single piececomprisi ng-a'trapezoidal shaped blank scored to-provide a centrally arrangedtriangular bottom portion and tn o triangular top portions connectedtosides of said bottom portion by intermediate rectangular side portions,reinforcing stayfiaps extend ing parallel with said side portionsadjacent the ends of the tree sidesof said bottom portion, and a thirdrectan ular side portion forming an extension o one side of one of saidtopmembers and having a closure flap adapted to be frictionally heldbetween the edges of said stay flapsand said bottom portion when folded,whereby only one free edge is providedat the, top and at the bottom ofthe folded triangular, container.

In testimony whereof ture.
